Wagon Brake.

IZT/VESS'S ideaal. tant @tutti @imita Letters vPatent No. 92,025, dated June 29, 1869.

IMPRYOVED- WAGON-BRAKE The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Beit known that I, DAVID EATON, of Rochester, in the county of Windsor, and State of Vermont, have invented. certain new and useful Improvements in Self- Acting Wagon-Brakes; and the ibllowing is a full, clear, and exact description ot the construction and operation of the same, reference being had to the accompanying drawing, making part of this specification, in which- Figure 1 is a perspective view of a wagon, with my brake applied.

Figure 2 is a bottom or plan view of same.

l Similar letters of reference indicate corresponding parts in both figures.

My invention consists in a novel construction ot' a wagon-brake and the auxiliary mechanism, wherebyl the operation ot' said brake is made more eiective, nd is placed more fully under the control of the river.

But the invention will be fully understood from the following description:

A A A A are the wheels.

B, the fore axle.

B', the rear axle.

C C are the holsters. y

To the rear one, C', is secured thebox or body represented in the drawing by the frame D, the front end of which is free to move back and forth upon the fore bolster, or rather upon the friction-roller c, confined upon said bolster by the staples c` c', in such manner that it (the roller) can t1"L vel laterally across the face of the bolster, as hereinafter explained.

E is a reach, composed ot' two pieces, the upper one of which is attached to the rear bolster, while the lower part is attached to the fore bolster, and both of them secured together by bolts c e, moving in slots e c.

To the lower portion of this reach is attached the brake-beam F, provided at each end with shoes or rubbers-ff. Or, it' desired, the brake may be'placed upon the upper side of the lreach E, resting upon the upper halt' of said reach, instead ot' being suspended iroin the lower portion, as is now shown in the drawings. But in this arrangement the braces F F must Still be connected with the lower-part ofthe reach, in

order to actuate the brake, and the .brake must be secured to the upper part of the reach in such manner as to slide upon the reach. v

H is a stop connected with and operated by the lever h, pivoted upon stake h', within convenient reach of the driver while sitting :in the front part of the wagon, as shown in tig. 1.

Ihe operation of my brake is as follows:

Under ordinary circumstances, I leave the lever h in a vertical position, andthe stop H withdrawn from between the end of the upper part of the reach and the bolster-.0, as shown in tig. 1. rIhen, if I wish to back the wagon, I thrust the top of the lever out, thus interposing the stop H between the upper portion of the reach and the bolster C, which eli'ectually prevents the lower part ot' the reach from being forced back, and, ofcourse, keeps the brakes oi the wheels;

but it' I wish the brake tn 'be applied by thc action of the horses crowding the tongue in a backward direction, I leave the lever in the vvertical position and the ,stop H withdrawn, as shown in black, tlg. 1, when .it

will be apparent thatany pressure applied to the tongue will be instantly exerted iu holding the brakeshoes or rubbers ff rmly against the wheels upon the rear axle B", the box or platform represented by D moving freely upon the friction-roller c, and allowing` the necessary motion of the axle B and bolster C, relative to the other parts of the wagon.

It will be observed,that by my arrangement of bolts c e and slots c c', I provide for the support and requisite longitudinal movement of that port-ion ofthe reach which sustains and actuates the'brake, without passing said reach through, and thus weakening the axle B. A

Having thus described my improvement, v What I claim as new, and wish to secure by Letters Patent, is t 1. The' arrangement ofthe bolster G,- stop H, lever h, and upper part oiI reach E, operating as set forth. 2. The combination of the reach E, brake F, `bolster G, stop H, and lever h, all arranged and operating substantially as shown and described.
